Abstract
In one embodiment of the invention, a method for obtaining a tomogram of an anatomical structure is disclosed. In one step, an anatomical structure is scanned using a scanning source and a scanning detector. Both the scanning source and detector are connected to a gantry. In another step, the speed of the gantry is altered during the scanning process. Additionally or optionally the frame rate of the scan can be modified in such step. In a particular embodiment of the invention, the speed of the gantry is altered in synchronicity with the respiratory signal of a patient. Using such a method, a tomogram of an anatomical structure is obtained.
